Trouble shooting (continued)
Problem Source Solution
Check the condition of the proportional amplifier.
F3, F6, F10 or F9 Fuses
are burnt. Check condition of fuse
Relays R3 or R 6 burnt
or not working.
Check to see if relays are cycling. Check contacts for burnt
conditions. If the contacts appear burnt, change out relay.
Ram Comes
Down, builds
pressure, but
will not return
up Machine in set up
mode.
Check run screen to ensure it is not in set up mode. This can
also be determined by a yellow run screen.
Pressure is not being
sensed. Check the pressure reading under the administration/
change plc values. The reading should be no more than 30
at idle. Also check the set point to ensure it is at 60 to 90. If
the set point is not correct, adjust to 90. If there is no
pressure being shown at idle, Check the wiring and plug
going to the pressure transducer for damage or loose
connections.
While watching the pressure screen, operate machine and
verify the pressure goes above the set point. Example: If
pressure only reaches 60 and set point is at
90, adjust set point to 55.
Continuously
getting TPS
errors. TPS sensitivity set to
low.
Reset TPS using the part and fastener for the job.
TPS set at high
pressure.
On older machines - set the TPS using min pressure. On high
speed machines it does not matter what force is selected.
Continuity pins and
spring worn causing
incorrect set
point. Check the springs and pins in the upper tool holder for
damage or collapsed springs.
P.C Error codes Numerical overflow
error
This error will come up when too much information had been
entered on any given line or too many characters. Example
would be TPS setting containing astrics. Look for this
occurrence on all information windows in the run screen,
admin screen, password screen, program screens.
If you cannot find the problem, reload the software and this
will reset default values.
